Abstract

A dishwasher includes a tub at least partially defining a treating chamber with an open face. A cover is movable between an opened and a closed condition to selectively open and close the open face, respectively. The cover has an inner surface confronting the open face in the closed condition. A treating chemistry dispenser is carried by the cover and includes a housing defining a cartridge chamber with a cartridge opening and a lid assembly selectively opening and closing the cartridge opening.

First claim

What is claimed is:

1. A dishwasher comprising:
a tub at least partially defining a treating chamber with an open face;
a cover movable between an opened condition and a closed condition to selectively open and close the open face, respectively, with the cover having an inner surface confronting the open face in the closed condition; and
a treating chemistry dispenser carried by the cover and comprising:
a housing defining a cartridge chamber with a drop-in cartridge opening,
a lid assembly movable between an opened position and closed position to selectively open and close the drop-in cartridge opening,
a cartridge motor assembly having a pump motor operably coupled to the cartridge chamber and movable relative to the cartridge chamber between an engaged position and a disengaged position, and
an actuator operably coupling the lid assembly to the cartridge motor assembly such that the pump motor is moved between the disengaged position and the engaged position upon operation of the actuator

wherein the actuator comprises multiple links connecting the lid assembly to the cartridge motor assembly.

2. The dishwasher of claim 1 wherein the multiple links draw the cartridge motor assembly from the disengaged position to the engaged position as the lid assembly is moved from the opened position to the closed position.

3. The dishwasher of claim 2 wherein the lid assembly is pivotally mounted to the housing for pivotal movement between the opened position and the closed position.

4. The dishwasher of claim 3 wherein at least one of the multiple links is pivotally mounted to the lid assembly.

5. The dishwasher of claim 4 wherein the at least one of the multiple links is pivotally mounted to the lid assembly at a location adjacent to where the lid assembly is pivotally mounted to the housing.

6. The dishwasher of claim 5 wherein the cartridge motor assembly comprises a motor frame carrying the pump motor and another at least one of the multiple links is connected to the motor frame.

7. The dishwasher of claim 6 wherein the another at least one of the multiple links is pivotally connected to the motor frame.

8. The dishwasher of claim 1 wherein the actuator is carried by at least one of the lid assembly and the housing and is moveable between a locked position and an unlocked position to lock and unlock the lid assembly relative to the housing, respectively.

9. The dishwasher of claim 8 wherein the actuator comprises a rotatable cam which is rotatable between the unlocked position and the locked position.

10. The dishwasher of claim 9 wherein the cartridge motor assembly comprises a motor frame carrying the pump motor and the rotatable cam is operably coupled to the motor frame such that rotation of the rotatable cam between the unlocked position the locked position moves the pump motor between the disengaged position and the engaged position.

11. The dishwasher of claim 10 wherein the rotatable cam bears directly against the motor frame to move the pump motor to the engaged position when the rotatable cam is in the locked position.

12. The dishwasher of claim 11 wherein the motor frame comprises a bias biasing the motor frame toward the disengaged position.

13. The dishwasher of claim 1 wherein the cartridge motor assembly comprises at least one of the pump motor and a motor frame mounting the at least one of the pump motor.

14. The dishwasher of claim 13 wherein the cartridge motor assembly comprises multiple pump motors and the motor frame mounts the multiple pump motors.

15. The dishwasher of claim 13 wherein the motor frame comprises a bias biasing the motor frame toward the disengaged position.

16. The dishwasher of claim 1 wherein the treating chemistry dispenser further comprises at least one treating chemistry cartridge inserted into the cartridge chamber through the drop-in cartridge opening and having a cartridge pump that couples to the pump motor when the pump motor is in the engaged position.

17. The dishwasher of claim 16 wherein the at least one treating chemistry cartridge comprises a collapsible container.

18. The dishwasher of claim 16 wherein the at least one treating chemistry cartridge comprises a non-collapsible container.

19. The dishwasher of claim 1 wherein the drop-in cartridge opening defines a plane, which is co-planar with the inner surface of the cover.
